Eco Start/Stop Function - Mercedes-Benz S-Class Operator's Manual

PLUG-IN HYBRID operation
288
The vehicle can be driven by the electric
motor alone up to a speed of approximately
130 km/h.
The vehicle is driven by the electric motor
alone only when all conditions for the auto-
matic engine switch-off are fulfilled.
Further information on the automatic engine
switch-off ( page 288).

Driving on inter-urban roads
The following phases are possible when driv-
ing on inter-urban roads:
rapid acceleration (boost mode)
R
constant energy consumption
R
energy recuperation
R
electric operation mode
R
A great deal of recovered energy may be
available, depending on the route profile. This
reduces consumption and emissions.
Highway driving
During highway driving, fuel consumption and
emissions are favorably influenced in partic-
ular by reduced power losses.
The internal combustion engine will be
switched off automatically, if:
the driver removes his foot from the accel-
R
erator pedal in drive program E and a speed
of 130 km/h is not exceeded
the driver removes his foot from the accel-
R
erator pedal in drive program E+ and a
speed of 180 km/h is not exceeded.

switch-off ( page 288).

R
perature
the driver's seat belt is fastened and the
